useful VIinproveinents in ll'indows, of which.

thc following is a specification.

This invention relates to .improvements in windows. and has referencevmore particularly, although not exclusively, to car winfy (lows. v

Certain features of improvement relate to the sash traine, which isconstructed of sheet metal suitably bent to forni hollow Stiles andbars. reinforced to secure suiiicient strength ima rigidity.,

Other .features ot' improvement relate to a novel means of attachingasash lock, with nreaxis"whereby the latter is caused to co operate withthe sash guide in effecting a snug lit of the sash in the guide, andstill other ininor features of improvement will hereinafter appear fromthe following. description of the invention.

illy invehtion will be readily understood,`

both with respect to its structural features andthe mechanicaladvantages and iin# provenients secured thereby, when considered inconnection with the,4 accompanying drawings illustrating soinepracticalenr bodiinents thereof, in which- Figure l'isan elevational View of a.portion. of a window frame or casing With the sash therein, the partsbein broken away both horizontally and vertically andthe base members ofthe inner-sash guides appearing in vertical section. Fig. 2 is. a verftical transverse section on the line 2 2 of 4I" ig. l, viewed in thedirection indicated by the arrows, and also showing a section of thesill and my improved sash-cushioning device monnted'thereon. Fig. 8 is acrosssectional detail on .the vline 3-3 ofJFig. l, .looking in thedirection indicated by the arrows Figffl is a View similarto Fig. 3, butshowing ldifferent forms of bent sheet metal' sash guides. Fig. 5 is afragmentary front elevation of the lower corner part of the sash andsill shown in Figg2, viewed in the direction indicated by the arrow 5 inthe latter figure. Fig. 6 is a fragnientary outer edge elevation of thesash and its guides, as viewed from-"theleft of Figs.l 1

and 3. Fig. 7 is a detail sectional View.

showing the' arched `form of glazing strip.

Fig. S is a detail longitudinal sectional view y 'through one of thehollow stile members showing the cross sectional shape of one of the,Arivets which connects the overlapping poiilions of said stile member.

l Referring to Figs. lto 3, inclusive, "and o and ti, 1 designates thesill, and 2 and 3 between them nido-grooves in which the Stiles ot thesasl are adapted' to slide. The guide-strips 2 and 3 are shown assubstanon 'their outer sides lat' -ally projecting flanges by which theyare secured to the jainb or casing by screws 4. In Fig. Ll, theguide-strips 2 and 3i are formed with inclined or oblique portions 2band 3D, through which pass in an oblique or inclined direction thesecuring screws 5, this construction aii'ording 'a simple .means ofinsuringa .snug sliding tit of the sash in its guides' after the sashhasbeen inserted, by ,simply additionally turning up the screws 5. 6designates as an entirety the upper and lower horizontal sash bars, and7 the side bars or stiles of the sash, which are in all cases-formedfrom a sheet metal stripor a seamless tube bent tothe require-dcrosssectional shape and provided with. an inder or stop for the marginof the glass 9.

channel-strips l0 of rubberor rsimilar ins the sash by glazing strips11, each of these strips comprising a transversely elastic metal stripsubstantially triangular shaped in cross-section andrhaving inner andouter lips llvand 11b (Fig. 3) adapted to bear against the adjacent sideof the insulator l0, 'said strip being secured by a series of screwsstrip. and tapped into the adjacent inner wall of the sash stile or bar;saidv screws vvpneilierably bein screwed into thiol: short riiets 13 bywhich the overlapping sections constituting the inner iva-ll of thestile lare l secured together.

The tenons (il and 62, as best' fil) saslrmeniber and,the angle-piece vertically or horizontally,` s the case may be, towardtheedge of the plate. to eiect the entrance of the other tenon to itsproper Vposition in the other member. of the sash. For instance, theupright limb of thelangle piece 28 aft the lower left handcornerof Fig.1 is slotted, mortised or recessed from its upper end downwardly atleast to the bottom edge of shown in Fig. 2, are inwardly offsetrelatively to the plate 60, and the lock-casing 56 is attached. to saidplate as by screws 65. To relieve 'the said screws of strain, l. preterably extend the upper-end of theplite 60 and overturn the same, asshown at 66 (Fis.

2l to forni an abutment for the'upper edge of the lock-easing 56; whilethe lower edge of the plate G0 to one side of the tenori 62 is likewisepreferably extended'und'tiirned up to Forni a shoulder or abutment6T`(Fig. 2) iol' the lower edge of the lock-casing, By this4 means allvertical strains imparted to the lock-easingthrough the plunger arereceived and resisted by the integral abutnients 66 and 67 of the plateG0; and consequently all the screws are relieved of such strain.

While the plate' 60 as above described constitutes a hase or support forthe lockeasing, it also performs an additional and valuable function asa corner iillet or reinforcement for 'the corner joint of the sashframe, thus permitting the use of relatively narrow Stiles and barswithout detracting from the strength and rigidity of the sash frame, andthus permitting, through the employnent of narrow stiles and bars, alarger totalarea of glazing than'would otherwise be possible, y. Byreference to Fig! 6 it will be observed that tlieopeningr 68 in thesash-guide inem-` ber 2 through which the locking plungers 57 of thelock enters is provided with an inclined Wall 69, and the face of theplunger 57 adjacent thereto is correspondingly inclined or beveled, asshown'atTO, the end' of the plunger 57 being shown in elevation.Furthermore, the cross-section of the plunger is somewhat. smaller thanthe area of the opening. B v reason ot this construction, when theplunger is engaged with the opening, the wei gli t of the sash acting;rthrough said plunn ger causes `the inclined side T0 of the plun ger toride down the inclined edge 69 ofthe opening', .f'liich action forcesthe. Sash ster ally toward the opposite sagshuide 3. thus "producing asnug it between said guidefand the sash.

lvl/ith reference to the described internal reinforcement of the sashframe members, il.

maybe noted that, wliile'l have illustrated this reinforcement asapplied to both the Stiles and hars, it is 'of especial advantage .in

its application to the horizontal bars, since they are subyected to thegreater strain, the Stiles being to' some extent supported through theirengagement with the guides.

While I have described and illustrated my improvements as applicable towindows,` yet I do not limit them to this particular appli.- eation tothe extent that the various features `lot' constructionare or may beapplicable to analogous structures, such as doors, panels.

and the like.
